    // Do any additional setup after loading the view, typically from a nib.
    // 练习1:
    TouchView *touchView = [[TouchView alloc] initWithFrame:CGRectMake(10, 10, 355, 200)];
    touchView.backgroundColor = [UIColor yellowColor];
    [self.view addSubview:touchView];
    
    // 1.响应者链
    // 触摸TouchView时
    // 检测顺序: 硬件 -> Appdelegate -> UIApplication -> UIWindow -> UIViewController -> self.view -> TouchView
    // 响应顺序: TouchView -> self.view -> UIViewController -> UIWindow -> UIApplication -> AppDelegate -> null
    // 如果所有的响应者都无法响应该事件, 则这个事件会被舍弃
    // 两种检测响应者的方法
    // 1.Category 实现 touchBegin的方法
    // 2.nextResponder
    
    // 例:
    // 1. 响应者不要出边界,出边界的响应者无法响应
    // 判断当前的点, 在谁的范围内 pointInside:withEvent:
    BOOL isInside = [touchView pointInside:CGPointMake(0, 0) withEvent:nil];
    NSLog(@"%@", isInside ? @"YES" : @"NO");
    UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];

    button.backgroundColor = [UIColor greenColor];
    [touchView addSubview:button];
    [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
    // 2.button的点击方法如何实现
    // button点击效果, 通过UIResponder对应的方法实现
    // 3.pointInside重写, 实现失去响应能力(return NO)
    
    
    // 轻拍手势

//    UIPanGestureRecognizer

//    UISwipeGestureRecognizer
    // 捏合
//    UIPinchGestureRecognizer
    // 旋转
//    UIRotationGestureRecognizer
    // 屏幕边缘手势
